Project Black Sunshine - The 300bhp NA
Yes, main bearing was fouled by some contamination. Current theory is that some loose metal was in my remote oil filter tree/cooler set up and that I didn’t adequately flush it out after it sat in the lock up for over a year. The debri from the damaged bearing spread throughout the motor damaging all crank and cam journals. Engine has been fully stripped and now going through a fresh rebuild at TDI. This was a very costly mistake and to say I’m gutted is an understatement!

NEC 2025 update
Cars look great, thanks for promoting the Z32 and our club! Gutted that I couldn’t join you but my motor is still at TDI.

Yes, they offer all sizes. Mine were 200mm long with 8 (front) and 6 kg ratings.

Refurbed the front Coilovers today. After many years they were looking a bit tatty although still functioning well. New springs, top pillowballs freed up and relubed, and given a good clean. Before and after photos -

Not yet, still waiting for TDI to finish the inspection. While the engine is out I’m taking care of a few small jobs. New dual air filters rather the HKS set up, power steering lines no longer leaking, horn wiring fixed, and a few cosmetic jobs.

Romain at RaceCal is very good at his craft and a genuine nice guy. Highly recommended

Motor stripped and dropped off at TDI. Should have some answers by next week. Oil looked good so don’t think anything too bad happened but time will tell…

Hate to report this but ran into problems during mapping. Tuner noted power drop off at 6k on multiple runs then detected ticking sound. The consensus with RaceCal and TDI is to pull the motor for inspection. Car is on the way back home tomorrow and I will tear it down and send the long block back to TDI for inspection. Will update as things develop.

Thanks Andrew!

Can anyone tell me what gets mounted to this spot? Assume it monitors flywheel speed for motor RPM but wasn’t present on my old transmission.

Tune scheduled for Sept 1 by RaceCal using TDI’s dyno. Will post the results. Great to see there are other owners chasing the elusive NA power!
